6 Claims.

This invention relates to new and useful improvements in pouring attachments for containers and relates to my copending application Serial No. 92,199, filed May 9, 1949, now Patent No. 2,558,575, dated June 26, 1951.

The primary object of the present invention is to provide a pouring attachment including a pouring spout having a cutter formed therewith that will punch out a small piece of metal in the upper wall of a container and which cutter is so constructed as to permit the piece of metal punched out to remain attached to the upper wall of the container.

Another important object of the present invention is to provide a pouring attachment of the aforementioned character wherein the pouring spout includes a downwardly tapered portion joined with the cutter so that as the cutter and the tapered portion are forced. into the upper wall of a container the edges defining the opening so formed will yieldingly grip the spout to support the container relative to the attachment.

Yet another object of the present invention is to provide a pouring attachment for containers including a spout having a vertically inclined dispensing end that slopes downwardly toward the interior of a hollow body suporting the spout so that any liquid in the spout will drain toward the body when the body is supported in a substantially vertical position.

Another object of the present invention is to provide a pouring attachment for containers involving a novel and improved vent means for increasing the efficient pouring of'liquid from a container housed within the attachment.

A further object of the present invention is the provision of a pouring attachment for containers involving a hollow body adapted to receive and retain a container therein and an insulating sleeve within the body for embracing a container so that the outer periphery of the case will not become cold under refrigeration and thereby preventing or restricting the formation of condensation on the outer periphery of the body.

A still further aim of the present invention is to provide a pouring attachment for containers that is simple and practical in construction, strong and reliable in use, small and compact in structure, neat and attractive in appearance, efficient and durable in operation, inexpensive to manufacture, and otherwise well adapted for the purposes for which the same is intended.

Other objects and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure l is an elevational View of the present invention;

Figure 2 is a plan view of Figure 1;

Figure 3 is a vertical sectional view taken substantially on the plane of section line 3-3 of Figure 2;

Figure 4 is a horizontal sectional view taken substantially on the plane of section line i-4 of Figure 3;

Figure 5 is a horizontal sectional view taken substantially on the plane of section line 5-5 of Figure 3;

Figure 6 is an enlarged detail vertical sectional View showing the pouring spout and the cutter formed therewith;

Figure '7 is a vertical sectional view taken substantially on the plane of section line l"! of Figure 6; and,

Figure 8 is a vertical sectional view of the present invention in slightly modified form.

Referring now to the drawings in detail, wherein for the purpose of illustration, there is disclosed a preferred embodiment of the present invention, the numeral H3 represents a hollow body or case of any suitable material, such as plastic, stainless steel or the like, having an open bottom and an upper end wall I2. The body lil may be cylindrical and is preferably formed with a plurality of flutes or hollow vertical ribs I i that will aid in yieldingly gripping and holding a container or can [6 within the body.

The upper wall [2 is formed with a central recess It in its lower face in which there is mounted an arcuate vent tube 26 having a downwardly curved end extension 22 that extends through and which is frictionally fitted in a downwardly curved opening 23 in the end wall I2. The lower downwardly and inwardly tapered end 25 of the extension 22 terminates in a cutter 28 having a pair of diametrically opposed v-slots 36 therein whose edges are inwardly beveled for penetrating the upper wall 32 of the can It as the body i0 is forced down upon the can or as the can is forced into the body.

The inward bevel of the edges defining the slots 39 will force the material of the wall 32 cut or punched by the cutter to bend downwardly but still remain attached to the wall 32. Furthermore, the tapered end 25 will expand the edges defining the opening made by the cutter 28 whereby the edges will yieldingly grip the extension 22 to aid in supporting the container within the body I0.

The upper wall 12 is formed with an additional central recess 34 in its upper face that slidably receives a finger grip 36 at the upper end of an ejecting shank 38. A pressure plate 40 is supported at the lower end of the shank 38. The wall 12 is provided with a reinforced axial bore 42 that slidably receives the shank 38. As the finger grip 36 is forced into the recess 34, the pressure plate 40 will engage the upper wall 32 of the container to force the container from the open bottom of the body 10.

The inner surface of the body I is coated with an insulating material or receives an insulating sleeve 44 that will tend to prevent the formation of condensation on the outer surface of the body and thereby permit handling of the device in a convenient manner.

A substantially V-shaped tubular spout 46 is supported by the body [0 and more specifically the end wall l2. This spout comprises an upwardly and outwardly inclined leg portion or dispensing end 48 that extends outwardly through and which is frictionally fitted in an upwardly and outwardly inclined opening 50 in the end wall l2. The vertical leg portion 52 of the spout 46 is located within the body It and includes a downwardly extending, inwardly tapered end portion or shoulder 54 that terminates in a cutter 56 having a pair of diametrically opposed V-shaped slots 58 cut in its lower edge.

The leg portion 52 is provided with an opening 60 adjacent its end portion 54 and the edges 62 defining the slots 58 are inwardly beveled, as shown in Figures 6 and 7, so that as the cutter 56 penetrates the upper wall 32 of the container l6, material M will be struck from and folded downwardly into the container without separating from the wall 32 (see Figure '7). Furthermore, the portion 54 will expand the edges defining the opening formed in the wall 32 by the cutter 56 so that the edges will yieldingly grip the leg portion 52 to aid in supporting the container within the body.

Attention is now directed to Figure 8, wherein the air vent means 200. is shown as extending through a downwardly curved recess or passage [8a in the upper wall 12a of the hollow body a to communicate the interior of the body with the central recess 34a in the upper wall I2a.

The lower vertical portion P of the vent tube 2la terminates in a tapered portion 26a and a cutter 28a having slots a which function similar to the parts 36, 28 and 30 previously described.

One of the outstanding features of the present invention is the spout structure involving an expansible portion 54 which not only assists in gripping the container in place, but also acts as a full and complete seal against leakage of the contents through the perforation without use of a washer or any other such device.

It is noted that the overall height of the case or hollow-body is slightly shorter than a container that is to be received therein, so that as the case, with container inserted, is set on a table, the container will not have the tendency to drop out which would undoubtedly occur if the case were longer than the container.

The vent and spout inserts may be formed in two or more parts which are screwed together.

Having described the invention, claimed as new is:
